Gauze shed: The shed is a metal frame used to carry yarn counts and lead the yarn to the loom for weaving. The form is divided into two types.

A yarn shed: a yarn shed is a metal frame used to carry yarn counts and lead the yarn to the loom for weaving. The form is divided into two types. The first category is the top yarn shed. It sits on the top of the loom. With more, the load on the ceiling will go wrong. The second category is a floor shed. The floor shed covers a lot of land, but the advantage is that it is convenient to barge and there is enough space for barge.

Note: The tail end of each yarn usually has a few inches of yarn exposed from the paper tube, which is intentionally made when turning the yarn. Therefore, before weaving a yarn, it can be barbed at the yarn end of another new yarn, which can reduce the number of downtime caused by yarn supply.

B Top stop: The top stop is located on the top of the loom's shed. After each yarn is pulled out by the yarn, it passes through a top stop. When the yarn tension is too high, the yarn pulls the top stop and immediately closes the weaving mechanism; When the yarn is leaked (flying) or the tension is too light, the stopper can also be used to stop the machine to avoid yelling or yarn breakage caused by excessive yarn tension.

C Conveying: Divided into positive conveying and negative conveying.

1 Active conveying is to use the conveying belt to control the speed of yarn feeding into the loom (controlling the weight of the cloth). On the other hand, the yarn speed of each module can be controlled to improve the quality of the product.

2 Negative conveyance is that the knitting needle freely draws only the yarn from the yarn into the machine. For some cloths that cannot be fed at a fixed speed, such as yarn-dyed jacquard, it is just relatively common.

D Midway stop: Before the yarn enters the yarn feeder, it must go through the midway stop. When the yarn tension is too low or the end breaks, a signal is sent to stop the weaving mechanism immediately.

E Yarn nozzle (steel shuttle, yarn guide): The yarn enters the hook of the knitting needle after passing through the ground yarn nozzle. It fixes the angle and position of the yarn entering the machine. Important position, in addition to the earth cannon made in Hong Kong, the yarn nozzle can prevent the needle tongue from jumping and close the hook, so that the knitting needle cannot catch the yarn.

F Syringe: Syringes or dials are divided into upper and lower syringes. The name of the single-sided machine is because there is only the lower plate and no upper plate. The lower plate is a round metal cylinder, and the upper plate is a round metal cymbal. The diameter of the two is the same, and the diameter is what we call the loom inch size, such as 26G30 ". The dial is engraved with many pits. Each pit can hold a knitting needle, and the stitches are exposed outside the barrel. The arrangement of the lower dial needle is vertical to the ground, and the upper needle is parallel to the ground.
